+Apollo Server is a GraphQL Server implementation that provides all the features you need to take your GraphQL API from prototype to production.
 
-<h2 id="run">Run your server</h2>
\ No newline at end of file
+We need to install two packages when setting up Apollo Server:
+
+```bash
+npm install apollo-server graphql --save
+```
+
+* [apollo-server](https://npm.im/apollo-server): This is the Apollo Server library.
+* [graphql](https://npm.im/graphql): This package is the JavaScript reference implementation for GraphQL. It's needed for Apollo Server to function as intended.
+
+Apollo Server has various variants to accomodate easy integration with existing applications. Some of them are `apollo-server-express`, `apollo-server-hapi`, `apollo-server-koa`, etc.
+
+```bash
+npm install apollo-server-express graphql --save
+```
+
+To quickly set up a GraphQL server using Apollo Server, a schema type definition and corresponding resolver is needed. The schema type definition represents your GraphQL schema, while the resolver is a function that implements the schema.
+
+Check out a simple Apollo Server example below:
+
+```js
+const { ApolloServer, gql } = require('apollo-server');
+
+const typeDefs = gql`
+  type Query {
+    name: String
+  }
+`;
+
+// Resolvers define the technique for fetching the types in the schema.
+const resolvers = {
+  Query: {
+    name: () => 'graphql',
+  },
+};
+
+// In the most basic sense, the ApolloServer can be started
+// by passing type definitions (typeDefs) and the resolvers
+// responsible for fetching the data for those types.
+const server = new ApolloServer({
+  typeDefs,
+  resolvers,
+});
+```
+
+In the code above, we imported the `ApolloServer` class and `gql` tag from the `apollo-server` package.. They serve the following purpose:
+
+* **ApolloServer**: The `ApolloServer` class instantiates and starts a new GraphQL server.
+* **gql**: The `gql` tag is a JavaScript template literal tag that enables syntax highlighting for our schema.
+
+<h2 id="write-schema">Write your graph's schema</h2>
+
+Every GraphQL server runs a schema at its core. A schema defines types and their relationships. The specifications of the types of queries that can be run against a GraphQL server are defined in a schema. Let's design the schema for our app.
+
+GraphQL schemas are at their best when they are designed around the needs of client applications. In fact, this is called **Schema First Development**, an approach for building applications with GraphQL that involves the frontend and backend teams agreeing on a schema first, which serves as a contract between the UI and the backend before any API development commences.
+
+In our app, we need to provide the following features:
+
+* Fetch all upcoming rocket launches.
+* Fetch a specific launch.
+* Fetch upcoming trips.
+* Users should be able to login to be authorized to book and cancel launch trips.
+* Users should be able to book launch trips.
+* Users should be able to cancel launch trips.
+
+These features influenced the derived types for our Schema as shown below:
+
+_src/schema.js_
+
+```js
+const { gql } = require('apollo-server');
+
+const typeDefs = gql`
+  type Query {
+    launches(pageSize: Int, cursor: String): [Launch]!
+    launch(id: ID!): Launch
+    user(id: ID!): User
+  }
+
+  type Mutation {
+    bookTrips(userId: ID!, tripId: [ID!]): Boolean!
+    cancelTrip(userId: ID!, tripId: ID!): Boolean!
+    login(email: String): String
+  }
+
+  type Launch {
+    id: ID!
+    cursor: String
+    year: String!
+    date: String!
+    mission: Mission!
+    rocket: Rocket!
+    launchSuccess: Boolean
+  }
+
+  type Rocket {
+    id: ID!
+    name: String!
+    type: String!
+  }
+
+  type User {
+    id: ID!
+    email: String!
+    avatar: String
+    trips: [Launch]
+  }
+
+  type Mission {
+    name: String!
+    missionPatch: String
+  }
+`;
+
+module.exports = typeDefs;
+```
